We actually came to swim with dolphins. The taxi cost us 280 paso, and swim was $129 US dollars a person. Extra $75 for a picture. Camera in the swim area was not allowed. Had I know that I probably wouldn't have come. Dolphin swim was interesting. I found dolphins intimidating as they are meat eaters and have large teeth. The manatee swim I found more is impressive. Big water cows. The park closes early. Like 5pm. One person said jokingly that on rare occasions salt water crocodiles have come in at dusk. Not sure on that. I did see an iguana. This is massive park with lots of stuff to do, like zip lining, diving , snorkeling,.. shore is sandy and shallow. Our package came with quick buffet which was simple but good. Water at pier distance looks deeper like 20-30ft and I could see what looked like large 2ft long yellowfin tuna zipping back and forth along the edge of the net pens. Originally when the park opened it was cheaper, like $20. But at current price we paid it seemed over priced. Much like a lot of Mexico in last few years has gotten more expensive as average income has gone up, and foreigners are now buying property... another guest I was talking with had snorkeled the lagoon and seen the impressive tarpon. Also seen the sculptures out at depth. If I was to do this again, I'd plan to come early.
